A Fixed Point Iteration Technique for Proving Correctness of Slicing for Probabilistic Programs
Torben Amtoft, Anindya Banerjee · arXiv (Cornell University) · 2024
When proving the correctness of a method for slicing probabilistic programs, it was previously discovered by the authors that for a fixed point iteration to work one needs a non-standard starting point for the iteration. This paper presents and explores this technique in a general setting; it states the lemmas that must be established to use the technique to prove the correctness of a program transformation, and sketches how to apply the technique to slicing of probabilistic programs.
